Modelling seed germination in response to continuous variables: use and limitations of probit analysis and alternative approaches por Hay, Fiona R., Mead, Andrew, Bloomberg, Mark

“…Probit-based models relating a proportional response variable to a temporal explanatory variable, assuming that the times to response are normally distributed within the population, have been used in seed biology for describing the rate of loss of viability during seed ageing and the progress of germination over time in response to environmental signals (e.g. water, temperature). …”
